Insulated Plasterboard (Dot & Dab option)

Each board features a rigid insulation backing, typically PIR or EPS, bonded to premium plasterboard, providing both insulation and a ready-to-decorate surface. It’s an ideal solution for internal wall upgrades in homes, extensions and commercial refurbishments where retaining space is important while still achieving modern thermal performance standards.

Can you dot and dab insulated plasterboard?

Yes, you can. Dot and dab insulated plasterboard is designed specifically for this method of installation. Adhesive is applied in controlled dabs across the wall surface, allowing the board to be positioned securely while creating a continuous layer of insulation behind the finished surface. This technique is popular with both tradespeople and homeowners as it offers a quick, clean installation process with minimal disruption. When fitted correctly, it provides strong adhesion, improved airtightness and long-term energy savings.

This dot dab insulated plasterboard also helps reduce condensation risk on cold external walls and improves comfort levels within the room.
